Query regarding CPU frequency


rudrax

Recommended Posts

I have a mobile Intel core i3 processor whose rated clock (frequency) is 2266 MHz. My queries are:

  • When should a CPU attain its rated frequency?
  • Can the CPU frequency reach its rated value when CPU uses is 0-2%?
  • Can CPU frequency be made to vary in a way that will be directly proportional to the CPU uses?

1. It runs at the maximum clock speed as required. Its like the 'Interactive' governor in Android. It'll boost up your clock speed when you need it, and keep it low when you don't. However, your power plan will also have some effect on the clock speed.

2. I do not think so as 0-2% workload is not very demanding, but I could be wrong here.

3. It already varies with the workload, so you need not to worry about it. If you should feel compelled, you can adjust the clock speed by going to 'Advanced Power Management' > 'Processor Power Management', and setting in your desired values.

Thank you for your response.

I use the little core temp program. http://www.alcpu.com/CoreTemp/ Interesting to watch the the speeds and %load ..http://i48.tinypic.com/nec0uu.jpg . as well as temperature on my win8 Lenovo.

I've that program already. It just monitors.

Frequency needs to be clocked at the BIOS. ;)

And my current BIOS will never allow that.

Can't comment on something I've never set eyes on - however, there's no system that I've never yet found a workaround for.

That said, though - I'm firmly against needling with the clocking of a laptop. The laptop that I presently use is a monster and can very easily be overclocked - yet, I have not clocked it. In fact, whenever I come across a Customer's system that's been clocked - I ensure that it's reverted.

Overclocking a laptop is not the way to go - there are far superior ways (without the side effects of clocking) such as opting for a lighter kernel, migrating to UEFI, formatting into GPT, configuring & customizing, etc., etc.

I set the "maximum processor state" to 80% in the power management and it seems working now. CPU frequency is not going high on lower CPU uses.

Your processor might not be fully utilized then.

I did that for on battery and for plugged-in, it's still 100%.
